Domain Checker FAQs

Question 1

What is Domain Checker?

Accepted Answer

Domain Checker is an efficient software tool designed to determine domain name availability. It leverages a powerful hybrid approach combining fast DNS lookups with accurate RDAP/WHOIS verification.

Question 2

How does Domain Checker ensure accuracy for availability checks?

Accepted Answer

It uses a hybrid verification method. First, a rapid DNS lookup identifies domains that are clearly taken. For domains that don't resolve via DNS, it then performs a more thorough RDAP (with WHOIS fallback) verification to confirm their actual availability.

Question 3

Can I check multiple domain names simultaneously?

Accepted Answer

Yes, Domain Checker supports bulk domain checking. You can check up to 100 domains in parallel, utilizing efficient parallel processing for optimal throughput and faster results.

Question 4

Does it help find names across different TLDs?

Accepted Answer

Absolutely. The `check_names` function automatically expands a base name (e.g., 'myproject') across popular Top-Level Domains (TLDs) like .com, .io, .dev, or any specific list of TLDs you provide, making it easy to find suitable options.

Question 5

What's the difference between `check_domains` and `check_domains_quick`?

Accepted Answer

`check_domains` performs a comprehensive check using both DNS and RDAP/WHOIS for maximum accuracy. `check_domains_quick` is a faster, DNS-only check. While quicker, it may produce false positives for available domains as it lacks full WHOIS verification.
